If You Gently Twist Your Earlobe, It Does Not Remain

Question

If you gently twist your earlobe, it does not remain distorted because it contains
A) collagenous fibers.
B) elastin fibers.
C) reticular fibers.
D) adipose tissue.
E) loose connective tissue.

Accepted Answer

Elastin fibers provide elasticity to tissues and allow them to return to their original shape after deformation. Therefore, the earlobe does not remain distorted after being gently twisted because it contains elastin fibers. Collagenous fibers provide structural support and are not as elastic as elastin fibers. Reticular fibers are also involved in structural support but are thinner and branch more extensively than collagenous fibers. Adipose tissue is a type of loose connective tissue that stores fat and provides insulation and cushioning. Loose connective tissue serves as a framework for organs and tissues and contains a variety of cells and fibers.
